I'm digging a lot of deep nail and bolts (but no coins) that are sounding in around Ferrous 11 to 14 and in the 30s on the conductivity. I'm running in MineLab's trash pattern and have my machine set to High Trash and Difficult Ground.
 
Just some food for thought.

1. Swing speed. I don't know what your swing speed is, but you might play with that a little.

2. Circling the target and see what you hear. To me, consistancy of sound on a target is the best information my detector can give me.

3. Are a lot of these sounds coming at the "end" of your swing. I personally get a lot of these types signals when I'm starting back from the end of my swing and there's iron nearby.

4. Also what does the quickmask show you when checking the "iffy" target (see if the Fe shoots up into the 30's when your QM is in All Metal?) Make a mental note where you think the target should be, go in to Quick Mask All Metal and start to swing over the area again (just a wiggle) then start to move around the spot you think the target is and you should find your "nail" sound with those 34-45 type numbers off to the side.

5. Check those signals in Ferrous audio and see what turns up, if the iron is that bad. I still dig rusty nails too, but not nearly as many as I did starting out. For me the nail will have a longer, higher pitched sound with, for lack of a better term (a crackling or breaking up sound) to it when swinging one way, and a nice sound to it the other way. I dig 2-way signals, when I'm have a discrimination patter, even if I suspect a nail. Just one way signals I tend to play with a lot more before I dig and decide if I feel like finding out what it was.

Last Sunday I hunted a small yard and had a really nice sound all the way around. Fe numbers were riding a little high but I dug it anyway. Turned out to be a rusted square nut and a bent nail, I was really suspecting a silver mixed in with nails....as I'd dug a barber dime out not 2 feet away. I can live with that.

Let us know how its going.

Neb has very good advice in his post. I would add one term to Neb's description of an iron false. I call it harsh. The tones tend to quickly rise and fall and you don't get the smoothness of a non-ferrous target. Bent nails can sound very sweet though. I have dug quite a few that just sounded too good to pass up. Like Neb said, I can live with that. I also agree that the consistency of the tones as you sweep over a target is the best info you are getting. Iron target tones tend to change (come and go) slightly from sweep to sweep. The more you detect in iron patches, the more you will learn about the response of your machine.
 
HI NebTrac,

I'll try to see what I can answer of you questions. I really appreciate the fast response with suggestion!! Thanks!

1. Swing speed. I don't know what your swing speed is, but you might play with that a little.

I've been swinging slowly and trying to keep the coil brushing the ground.

2. Circling the target and see what you hear. To me, consistancy of sound on a target is the best information my detector can give me.

I've been circling the target trying see if I get a signal from more than one side. A lot of time I get a null with the signal at the end and wonder if it's a coin peeking out from under some iron.

3. Are a lot of these sounds coming at the "end" of your swing. I personally get a lot of these types signals when I'm starting back from the end of my swing and there's iron nearby.

Yes. But, I've been able to do the wiggle and have the signal run the entire length of the "hot strip"

4. Also what does the quickmask show you when checking the "iffy" target (see if the Fe shoots up into the 30's when your QM is in All Metal?) Make a mental note where you think the target should be, go in to Quick Mask All Metal and start to swing over the area again (just a wiggle) then start to move around the spot you think the target is and you should find your "nail" sound with those 34-45 type numbers off to the side.

This is something I have not tried. Will have to go out and experiment with it.

5. Check those signals in Ferrous audio and see what turns up, if the iron is that bad. I still dig rusty nails too, but not nearly as many as I did starting out. For me the nail will have a longer, higher pitched sound with, for lack of a better term (a crackling or breaking up sound) to it when swinging one way, and a nice sound to it the other way. I dig 2-way signals, when I'm have a discrimination patter, even if I suspect a nail. Just one way signals I tend to play with a lot more before I dig and decide if I feel like finding out what it was.

Thank you again for the Info!

I'm repeating a tip I read on here that helped me in iron.

Go to 2 tone ferrous. Also set the tone response to SMOOTH. The smooth tones was the key. It made the iron falses sound clipped/short compared to good targets. Then it comes down to believing the detector and moving on from those clipped sounds. I dug about half of them the first time out with these settings and they were all nails. That made a believer out of me. I stopped digging clipped good tones in high iron areas.
 
I have noticed that if you have your discrimination opened up too much,
I get a similar result. It seems if you open up the iron area the range of tones goes full circle
and starts to get high tones on iron.
If you open up the discrimination below 28 i think it is.
This can happen!
My suggestion would be to disc out everything below 28.
But i just run in the minelab coins mode,with the only mod being,remove the disc in the top R.H. corner.

I was running in coin mode and had removed the single line "ignore" area from the upper right of the screen. Now I'm running in the MineLab Trash Pattern.
 
Another thought I had while I was reading your responses. For me its kinda sublte, but see if you can't hear the null just "before" the hit. I don't always catch this, but there's some more info on your target there. I think once you get the hang of quickmask it helps gain you a lot of information.

I also have played with a signals long enough to make them diggable when I know I shouldn't have. Rusted bent nails, nails with washers attached and barbed wire, also fencing staples are my worst.

What type of sight are you hunting in?

Lastly, if you try 2-tone Ferrous, listen to your swing with a wide open screen (AM) and if your getting 4-8 hits of iron per one-way swing, that would be a place to be in 2-tone. For now that's how I've been hunting.

Do you have a coin garden? Mine really helped me with my sweep speed.

Yes, I'm getting nulls before the"hit". It makes me think that there's a coin at the edge.

I'm digging most high iron trash sites.

I'm getting a lot of iron hits per swing. Won't 2-tone still give me good signal at the edge?

Do you have a coin garden? Mine really helped me with my sweep speed.

No, I never tried a coin garden. How much room do you need? Also, if the space is free of iron once I dig it to "plant" the coins, I don't it will be a problem for me to latch on to them.

Bent L-shaped nails and some bolts and the dreaded fencing staples will fool any of us quite often I am afraid.As for the basic heavily rusted nails ,not as often.One thing that eliminates a lot of them is being a nice one way hit and nothing at 90 deg.Another indicator is if the target pinpoints several inches away from the "wiggle" location,most often strait in front and or strait behind said wiggle point.

The more desperate one gets to find deep silver the more iffy signals one chases and always ends up digging more iron/nails in the process.Any one who regularly finds deep silver in hard hit sites will be digging some iron and don't believe any thing else.It is possible to dig very little to no iron at older sites and still get deep silver but only by digging the perfect textbook silver signals and we all know they are few and far between at hammered public areas.

It has been my experience that I very rarely dig a deep silver thinking it could be iron but dig a number of iron targets thinking they are iron, but just maybe silver.I have dug a number of silver coins that only hit very well one way only, but were in between two iron targets and pinpoint mode confirmed this before digging.

Coins on edges will be a bit more clipped in their responses but still sound good and will pinpoint off to one side .Often the conductive numbers for on edge coins will be near where they are on the more flat lying coins but the ferrous numbers will be at 1-8 instead of the 12 range give or take a number.This is for moderate depth coins as all bets are off on extreme depth coins except to say I find they to will often hit at 1-8 ferrous and a bit smaller number than normal on conductive.

I must ad that the experiences I have shared were while hunting in conductive multi tones in factory coins mode with difficult on and deep & fast off with high manual sens.

I think we often want to hear/find silver so bad after a dry spell that we start thinking maybe,just maybe that nail signal could be a deep silver coin trying to hide from us.
This may sound a bit silly to some but will still help a person I believe,so here goes....
Take a couple of common silver dimes with you to your site and bury them at say 6" and 8" in a relatively clean location and give your ears a refresher course while testing your swing speed and settings.Sounds kinda like what a beginner would do but swallow the old pride and help your self out as it will help,Ray.
